I think by now everyone has seen the shooting at the Sikh temple. I'm including it here because right after 9-11 some Sikhs were killed because they were mistaken for Muslims. Apparently if you wear a turban that means you're Muslim.
Another one: A mosque in Joplin, Missouri has been burned down - for the second time this summer!
Last year a mosque in California was burned down.
An organization is putting up Islamorealism signs in New York, to expose terrorism.
